METHOD 0F MAKING SHEET METALWARE JOINTS Filed May 27, 1950 Patented Aug. 16, 1932 UNITED STATES AARON SHATKIN, OF BROOKLYN, NEW YORK METHOD OF MAKING SHEET 'METALWARE JOINTS Application led May 27,

The present invention relates to the joining of sheet meta-l shells or forms which make up the component parts of candle-sticks, salt shakers, fruit bowls, vases and similar class of articles. These articles are usually made up of spun or stamped shells or forms which arc soldered together. One of the objects.l of this invention, is to dispense with the soldering operations which are costly and require skill, and to provide a oint construction which will join the several parts of these articles in a simple, inexpensive and secure manner. Another object of my invention is to provide a joint which will not allow the joined parts from becoming dis-associated even by abuse. To these and other ends, this invention consists in the novel method and construction hereinafter described, illustrated and claimed.

In the accompanying drawing, forming a part of this application, similar characters of reference indicate corresponding parts in all the views.

Fig. 1 is a view partly in elevation and partly in section of a Candlestick showing an embodiment of my invention.

Fig. 2 is a similar view showing another embodiment thereof.

Fig. 3 is a similar view of a salt shaker showing another embodiment of my invention.

Fig. 4C is a fragmentary view of one of the shells or forms to be joined, showing the partially corrugated or crimped contact surface.

Fig. 5 is an enlarged sectional view of the joint.

Fig. 6 is an enlarged sectional view of the joint as adapted to water-t-ight compartments construction.

Fig. 7 is a View partly in elevation and partly in section of a vase showing embodiments of my invention.

Fig. 8 is a view partly in elevation and partly in section of a candlestick which is r made up of many parts, showing another embodiment of my invention.

I carry out this invention by corrugating or crimpingv corresponding portions of the contact surfaces of the shells or forms to be joined, passing an eyelet through all of said 1930. serial No. 456,079.4

shells or forms through perforations therefor provided, arranging the several parts to be joined, so that the corrugated surfaces engage or mesh, and then by closing the eyeletto lhold all the parts securely together. The eyelet will be either long or short, depending upon the number of parts to be joined together. The eyelet prevents the several shells or forms from becoming dis-associated, while the contact surfaces being engaged or meshed, j none of the several parts so joined can be turned about the eyelet independently.

Referring to the drawing, candle socket holder 16 and base 12 have their contact surfaces-corrugated or crimped with corrugations 25, and both partsof the candlestick shown in Fig. 1, are joined by an eyelet 10 passed through perforations 9. Washers 9 are provided as shown, to give greaterrigidity to the joint. Fig. 5 is an enlarged view of this joint.

The separate eyeletmay be dispensed with, by fashioning one of the parts to be joined to include an equivalent of the eyelet as is shown in the candle-stick ofFig. 2. The candle socket holder 16 has a nipple 11 extending downward from its bottom, and said nipple 11 serves as an eyelet. Flange 11 is formed by an eyelet closing or setting instrument.

In the construction of salt shakers, the compartment 17 used for holding salt must be salt tight; and in vases the compartment 12 must be water tight. The oint shown in Fig. 5 would be adaptable for such purposes should the hole 26 of the eyelet 10 be closed. I therefor cover the eyelet 10 with a cap 18, and the wat-.er tight joint is shown in enlarged section in Fig. 6. l/Vashers 9 are provided to give the joint greater rigidity. When the joint is made as shown in Fig. 5, the washer 9 and the flange 10 of eyelet 10, protrude above the surface of the bottom of Candle socket holder 16. In order to make a flush surface, the joined parts 16 and 12 should be provided and formed with depressed cups 27 and 28, as are the joined parts 13 and 17 shown in the enlarged view in Fig. 6.

The components 12 and 16 of the liquidholding compartment of the case shown in Fig. 7, are joined together by a joint similar to the construction shown in Fig. 5.

In the constuction of Candlesticks or other standards made up of many parts of the type shown in Fig. 8, all of the component parts may be securely joined by a long eyelet 19. All contact surfaces of candle socket holder 20 and part 21, parts 21 and 22, parts 22 and 28, parts 23 and 24, and of part 24 and base l5, are each crimped with corrugations 25, Y

and are meshed. Eyelet 19 prevents the component parts of the candle-stick from becoming dis-associated, and the' meshingl of the corrugated portions of the Contact surfaces of the several component parts prevents any of the parts of the standard from being able to be turned about the eyelet independently.

The articles of the class herein mentioned, constructed according to the present invention, have considerably greater strength against destruction than the same articles having soldered joints. The cost of manufacture of these articles are reduced by employing the method herein described, and n0 skilled` labor is required in the assembling operations.

I claim:

l. The method of joining any number of sheet-metal shells or forms, Which consists in perforating each of the parts to be joined, corrugating corresponding portions of all con tact surfaces, so that one part can engage or mesh with the othervpart with Which it is t0 be in Contact, passing an eyelet through the perforations, arranging the parts so that the corrugations engage or mesh, and closing the eyelet. Y Y

2. The method of joining any number of shells or forms made of sheet material, Which consists in perfor-ating each of the parts toV be joined, corrugating corresponding portions of all contact surfaces, so that one part can engage or mesh With the other part With which 1t 1s 1n Contact, passing a fastening means through the said perforations, arrangingthe parts so that the corrugations engage or mesh, and securing the fastening means. In testimony whereof, I have hereunto set my hand.

AARON SHATKIN.
